I tried CHS Treatment Shampoo (sulfate) about a year ago after seeing some good reviews. My hair absolutely loved it (I always use prior to my PT, and sometimes once every few weeks in the shower). So then I started cautiously playing with cones again and I've had no issues. I still use mostly CG products, but there are a few products with cones that my hair likes, so they're in the rotation.
